SHARING: DISCHARGE MECHANISM.

Specification of Letters Patent.

Patented Dec. 9, 1919.

Application filed January 16, 1915. Serial No. 2,620.

a simple, convenient and reliable device of.

the kind described in which the movements of the discharging mechanism may regulated to suit the material or product being. discharged and to avoid unnecessary bruising or disfiguring of the pieces passing through the device.

To this end my invention consists in the" novel construction, arrangement and C0111- bination of parts herein shown and described and more particularly pointed out in the claims.

In the accompanying drawings wherein like or similar reference characters indicate like or corresponding parts:

Figure 1 is a side elevation of my device. Fig. 2 is an end elevation of the same. Fig. 3 is an enlarged fragmentary elevation of the discharge spout and associated parts on my device with parts removed and broken away to more clearly show the construction.

Fig. 4 is a partial section taken substantially on line H of Fig. 3.

In the form shown in the drawings asuitableframe comprising a pair of pillars 11 is provided near the upper end of which a roller or sheave 2 is mounted adapted to operate as the end roller for a carrier belt 3 for conveying the formed material to my device.

As shown a shaft a is mounted in suitable bearings on the frame 1 or adjacent portions of the mechanism and provided with a gear wheel 5 adapted to mesh with and drive a gear wheel 6 rigidly attached to the supporting shaft of the sheave 2 for operating the conveyer belt 3. In the form shown also an air pipe 7 is provided above the c'onveyer belt for discharging coola'ir upon the material upon the belt to chill the same and thus rendering the pieces more brittle and pre venting their sticking together when discharged from my device.

My improved mechanismconsists of suit able apparatus arrangedto receive the mate rialfrom the belt 3 and discharge thelsanie into a suitable rece'ptableat themat c-nit operating tobreak and separate the severalparts passinglthrough mydeVice-and free ing them from the associated material.

in the form shown a shaft 8Qis mounted in suitable bearings 99 on the respective portions of the framel and an eccentricpon tion 10 is rigidly attached to, or formed integrally upon, the shaft 8 between the bearings 9. A trough 11 of any'suitable form or construction is provided to receive the material from the belt 3 and direct the same into the desired receptacles.

Any suitable means may be provideol'upon the trough 11 to engage the eccentric portion 10 of the shaft 8 to shake, the trough. As shown a bearing 12 is fitted to the eccentric portion 10 and provided with a face adapted to engage and fit against the bot tom of the trough 11 with suitable arms 14;

or other convenient. means extending on each side of the trough each provided with suitable means adapted to rig'idly secure thearm to the side of the trough. As shown the side walls of the trough 11 are each provided with suitable slots. 16 extending longitudinally of the troughsubst'antially parallel with its bottom to provide a suitable support for the trough and for the convenient adjustment of the bearing longitudinally of thetrough.

Suitable means are alsoprovided to en gage one end of the trough tohold the same in a suitable position. In the form shown a link 17 is pivot-ally mounted between the pillars 11 as at 18 and attached to the trough. 11 as at 19 thus permitting the free movement of the free end of the trough both longitudinally and vertically when the shaft 8 is rotated. In'the preferred form also a part 20 is provided upon the link 17 beyond the bearing 18 to counterbalance theweight of the trough toavoidvibration in the frame and secure the smooth operation of the device. In'the preferred construction a verticalslot 21 is provided in eachofthe pillars land each 'end of'th'e bearing 18 of the link 17 extends into the slots with asuitable nut 22 or other convenient means at the outer end of the bearing adapted to rigidly clamp the bearing in position on the frame to control the inclination.

In the preferred construction suitable means are provided for directing material into the trough. As shown a chute 24: extending from a point near the periphery of the sheave 2 to the bottom of the trough is pr vided and rigidly attached to the frame 1 by brackets 25 or other convenient means rigidly attached to the frame and chute. A guard 26 also extends across the trough and is rigidly secured to the walls thereof in position to engage and direct material from the belt 3 into the trough and prevent the movements of the trougn from unnecessarily throwing material passing therethrough.

Suitable means are also provided for rotating the shaft 8 to shake the trough. In the form shown a gear wheel. 2'? is mounted upon the shaft 8 cooperating with a gear wheel 28 rotatably mounted upon the frame 1 and rigidly connected to a pinion 29 which in turn meshes with a gear 30 rigidly connected to the sheave The severalparts are so constructed and arranged that any rotation of the sheave 2 will produce a rapid rotation of the ft 8 thereby rapidly oscillating the free end of the trough 11 the movements of the trough however may be controlled within certain limits by adjusting the position of the bearing 12 longitudinally thereof. Whei the bolt 15 is positioned at the end of the slot 16 adjacent the free end of the trough thus bringing the bearing 12 to the limit of its movement toward the free end of the trough, the movements of the trough are comparatively slight. As the bearing is moved toward the opposite end of the trough however it is obvious that the movement of the free end of the trough will increase rapidly owing to the relative positions of the bearing 12 and the fulcrumof the trough formed by its connection to the link 17.

Having thus described my improvement, it is obvious that various immaterial modifications may be made in my device without departing from the spirit of my invention hence I do not wish to be understood as limiting in *self to the exact form or construction.

W hat I claim as new and desire to secure by Letters Patent is:

1. In a device of the kind described, a frame, a shaft having an eccentric portion rotatably mounted upon said frame, a trough mounted upon the eccentric portion of said shaft and means for adjusting the position of said trough upon said shaft, in combination with a link connecting one end of said trough to said frame, means for rotating said shaft and means for directing material into said trough.

2. In a device of the kind described, a frame, a shaft having an eccentric portlon rotatably mounted upon said frame, a trough mounted upon the eccentric portion of said shaft and means for adjusting the position of said trough upon said shaft longitudinally of the trough, in combination with a link connecting one end of said trough to said frame, means for rotating said shaft and means for directing material into said trough.

3. In a device of the kind described, a frame,-a shaft having an eccentric portion rotatably mounted upon said frame and a trough mounted upon the eccentric portion of said shaft, in combination with a link connecting one end of said trough to said frame, means for adjusting the connection between said link and frame, means for rotating said shaft and means for directing material into said trough.

l. In a device of the kind described, a frame, a shaft having an eccentric portion rotatably mounted upon said frame, a trough, a bearing rigidly attached to said trough and extending transversely thereof intermediate its ends and mounted upon the eccentric portion of said shaft and means for adjusting the position of said bearing upon said trough, in combination with a link connecting one end of said trough to said frame, means for rotating said shaft and means for directing material into said trough.

5. In a device of the kind described, a frame, a shaft having an eccentric portion rotatably mounted upon said frame, a. trough attached intermediate its ends to the occentric portion of said shaft and means for adjusting the position of said trough upon said shaft, in combination with a counterbalanced link connecting one end of said trough to said frame, means for adjusting the connection between said link and frame, means for rotating said shaft and means for directing material into said trough.

6. In a device of the kind described, a frame, a shaft having an eccentric portion rotatably mounted upon'said frame and a trough mounted upon the eccentric portion of said shaft, in combination with a counterbalanced link connecting one end of said trough to said frame, means for adjusting the connection between said link and frame, means for rotating said shaft and means mounted upon said trough for directing material into said trough.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
